In the past hundred years,there have been frequent natural disasters worldwide,such as floods,droughts,typhoons,earthquakes,landslides,forest fires,or which some are made worse or even caused by human activities
这里的or which是打字错误吗,如果不是,or which 是什么用法呢?
显然是打字错误,or 应为 of:
In the past hundred years, there have been frequent natural disasters worldwide, such as floods, droughts, typhoons, earthquakes, landslides, forest fires, of which some are made worse or even caused by human activities.
【翻译】在过去的一百年里,世界各地频繁发生自然灾害,如洪水、干旱、台风、地震、山体滑坡、森林火灾,其中有些自然灾害是因人类活动而变得更加严重,甚至由其直接导致的。
of which some = some of which
